Wearable cardioverter defibrillator component assembly verification

Abstract

A wearable cardiac device for providing feedback during device wear includes a garment, tags disposed on the garment, and electrodes configured to facilitate sensing electrical signals associated with cardiac activity of the patient and/or delivering therapeutic pulses to the patient. Each electrode is configured for assembly into the garment in a respective predetermined position. At least one respective electrode includes respective local position feedback circuitry. Each respective local position feedback circuitry includes a position verification sensor configured to sense one or more tags and one or more local position feedback indicators locally disposed on the respective electrode and configured to provide a human-discernable feedback alert indicating whether the respective electrode is assembled into the garment in the respective predetermined position. The position verification sensor is further configured to activate the one or more local position feedback indicators based on whether the position verification sensor senses the one or more tags.
